UNITED sTATEs PERCY T. LENOIR, OF HATTIESBURG, MISSISSIPPI.

BUMPER.

Application filed June'16, 1S25. Serial No. 87,499.

To all w/wm 'it may co'rwr'n:

Be it known that I, Pnnor T. LuNoin, a citizen of the United States, residing at Hattiesburg, vin the county of Forrest and State of Mississippi, have invented a new and useful Bumper, of which the following is a specification.

This invention relates to bumpers especially designed for use in connection with motor Vehicles or the like, and aims to provide a novel construction where the strain directed to the bumperwill be distributed throughout the various elements forming the bumper to insure against breaking by its contact with an object.

Another important object of the inv'ention is to provide means for cushioning the blow directed to the bumper incident to the bumper contacting with an object.

A still further object of the invent-ion is I the provision of means whereby the bumper may be secured and supported by the cross bars of the chassis, eliminating the neeessity of securing the bumper to the Springs lor side rails of the chassis.

With the foregoing and other objects in view which will appear as the descriptior proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understoofd that changes in vthe `precise vembodiment of .the invention herein disclosechmay be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the dra-Wing: o

Figure 1 is a plan view of a bumper constructed in accordance with the invention and designed for use at the forward end of a motor vehicle.

Figure 2 is a sectional view taken on line 2-2 of Figura 1.

Figure 3 is a plan view of a bumper especially designed for use at the rear end of a motor vehicle.

Figure 4 is a sectional view taken on line 4.-11 of Figure 3. V

Referring to the drawing in detail, the reference character 5 indicates thevmain bar of a bumper employed at the forward end of a motor vehicle, the same being construoted of any suitable material and as shown, is Slightly'curved at points a'djacent to its ends.

As shown by Figur'e 2 of the drawing,

-rods 8 are provided and are Secnred to the main bar 5, the inner' portions of the rods 8 being housed by the tubular members 6. Mounted on the rods 8 are sleeves 9 that are positioned within the tnbular members 6, the' inner ends of the sleeves 9 acting as stops for the coiled Springs 10, the opposite ends of the coiled Springs eontacting with the bar as clearly shown by Figure 2 so that inward move-ment of the bar 5 will be restricted by the movement of the coiled springs 10 which will act to return the bar 5 to its normal position after the pressure thereagainst has been relieved.

In order to provide a dust-proof connection between the tubular members 6' and sleeves 9 Operating therein, washe-rs 11 are provided at the inner ends of the tubular members. The reference character 12 represents the forward transverse bar employed in connecting the side rails of a motor vehicle chassis, which bar is formed with suitable'v openings to accommodate the rods 8 of the bumper, the rods 8 being of lengths to extend appreciable distances beyond the inner surface of the bar 12, providing lspaces for the coiled Springs 13 that have their outer ends bearing against the nuts 1a threaded on the inner ends of the rods 8 so that the tensions of the coiled Springs 13 may be regulated.

The sleeves 9 are connected with the bar 15 that is arranged adjacent to the transverse bar 12 of thevehicle chassis so that the sleeves 9 will be held against movement. Thus itwill be seen that should the bumper be moved into engagement with an obstacle, the main barywould be force'd rearwardly against the tension of the coiled Springs 10 which would absorb the shock directed to the vehicle. As the pressure on the bar 5 isrelieved, the springs 10 will act to return 'the bar 5 to its initial position, the coiled Springs 18 restricting forward movementof the bar 5 to relieve the Springs 10 of undue strain which would be ordinarily directed thereto by the recoil.

Fignre 3 which illustrates a bumper especially designed for use as a rear bumper,

f bar and through which the comprises a main bar 16 to which are secnred the rods 17 that extend through tnbnlar members 18, the tnbnlar members 18 being` supported within the sleeves 19 that are provided with washers 20 to insnre against foreign matter entering` between the tubniar members and sieeves. Support-mg piates indicated at 21 are boited to the nndersides of the Chassis of a vehieie to which the bumper is to be secnred, and as shown, these s'-.ipporting` piates are provided with offset portions 22 and which are formed with openings, the opening's in the offset por'tions 22 being ot diameters to accommodate the rods 1? while the openings in the oi-set por tions 23 are ot diameters snfiicient to receive the sieeves 19. Coiied Springs -ft are positioncd within the sieeves 19 andhwe their inner en tact-ing with the tnbniar members 18, posite ends ot the coile'1 Springs eng'aging the offset portion 22. the onnosite sides arr j Springs that aiso eng the nnts 2G monnted on the threaded ef`J trem'ities of the rods 17 whereby the tensions ot the Springs may be regulated at the will ot' the operator.

Formed integral with the sieeves 1.9 are arms 27 'that have their inne:` ends extended to a point adjacent to the rear transverse bar 28 ot the vehicle 'frame Where they are boited to the bar 28 by means ot the boits 29. Arms 30 extend iateraiiy trom the sieeves 19 and provide means :tor snpporting the rear mud `quards or tenders indicated at 31, there being` provided bolts 32 that extend 'hrongh the arms 30 and 'enders.

The ofiiset portion 23 ot each bracket member has an inwardiy extended fiange 33 provided with a threaded openingI to accoin modate the set screw 3% that is adapted to contact with the sieeve 19 associated therewith to secure the sleeve against movement with respect to the bracket member.

From the toregoing' detail description, it is beiieved that the Voperation and use of .the device will be obvions, and that fnrther detail description as Vto the operation ot the device is unnecessary.

1. A bnmper including' a main bar, rods extending :troni the bnim'e=.' and secnred thereto, said rods having; tii'eaded inner ends, tubniar mci'nbers secored to the main rods operate, sleeves through which the rods opcrate, supporting men'mers having: opening's through which the rods move, coiicd sin'ing's disposed on oppositc sides of the siniporting` members for re'strictinnj movement ot' the main bar and rods connected therewith, and means tor adjusting the tensions of the Springs.
